My main interests are linked to interdisciplinary research on understanding dynamic socio-ecological systems, especially in relation to conservation of freshwater and marine biodiversity across India. I have been studying endangered Ganges River dolphins in the lower Gangetic floodplains in the state of Bihar in India. I have been working with the Vikramshila Biodiversity Research and Education Centre, Bhagalpur on river dolphins and other freshwater species in the Vikramshila Gangetic Dolphin Sanctuary region here. The Sanctuary is a stretch of the Ganga River in a complex, dynamic and contested floodplain riverscape, where human livelihoods and freshwater conservation needs strongly overlap. We work closely with local fishing communities in this area, involving them actively in the process of river conservation.
Along with my work on river dolphins and fisheries in Bihar, I have also been working in the Lakshadweep Archipelago(India), on green turtles, fish diversity, seagrass meadows and coral reefs the Lakshadweep Islands, with the Oceans and Coasts Program of the Nature Conservation Foundation, Mysore, India. I am currently doing my PhD research at the Ashoka Trust for Research in Ecology and the Environment, Bangalore, India. In addition, I help in and partly work on projects about riverine and marine fisheries, moths, plants, dugongs, freshwater fishes, grasslands, waterbirds, otters, bats and their biology and conservation. Other academic interests include population and community ecology, landscape ecology,geology and geography, environmental history, anthropology and the application of Bayesian statistical methods in ecological research.
